About us

The Cochrane Comparing Multiple Interventions Methods Group (CMIMG) was registered in October 2010. As of April 2019, it has a little over 100 members in Archie. CMIMG covers methodology of (1) network meta-analysis (NMA), and (2) overviews of reviews.

NMA, in the context of a systematic review, compares three or more interventions simultaneously using both direct evidence within studies and indirect evidence across studies.

Overviews of reviews use explicit and systematic methods to search for and identify multiple systematic reviews on a similar topic for the purpose of extracting and analyzing their results across important outcomes. The unit of searching, inclusion, and data analysis is the systematic review rather than the primary study.
